KSB is a centrifugal duct fan in an insulated housing for supply and exhaust ventilation of individual rooms, buildings in individual, collective housing and public utilities. Efficiency up to 950 m ³ / h. The compact design and sound insulation allow the fan to be mounted directly in the room above the suspended ceiling. Installation possible at any angle to the fan axis.

Building

The fan casing is made of galvanized steel sheet using 25 mm thick mineral wool. Round connectors are equipped with rubber gaskets. Bipolar asynchronous motors with an external rotor with backward curved blades were used. A protection against overheating with automatic restart has been built in. The engine uses ball bearings.

Speed control

Speed regulation can be done smoothly (thyristor regulator) as well as stepwise (transformer regulator). Fans can be connected by a pair of units to one controller, provided that the available power and working current will not exceed the nominal parameter in the controller.

The offer also includes S models - with an engine with increased power.
